About Megawatt per metre kelvin
The megawatt per metre kelvin (MW/(m·K)) equals exactly 10⁶ W/(m·K). A theoretical and research unit for modelling exotic or nanostructured materials: theoretical carbon nanotube axial conductivity predictions and astrophysical plasma heat transport can reach the MW/(m·K) range. No bulk engineering material approaches this value. 1 MW/(m·K) = 10⁶ W/(m·K) = 1000 kW/(m·K).
About BTU per hour per foot per degree Fahrenheit
The BTU/(h·ft·°F) equals (1055.05585262 × 9)/(3600 × 0.3048 × 5) W/(m·K) ≈1.7307 W/(m·K). Standard US thermal conductivity unit in ASHRAE Handbook and ASTM C1045. Copper: ≈223; carbon steel: ≈26; brick: ≈0.44; glass fibre insulation: ≈0.025 BTU/(h·ft·°F). 1 BTU/(h·ft·°F) = 12 BTU·in/(h·ft²·°F) ≈1.7307 W/(m·K).
